Hi Everyone! 

I am looking to see if there is anyone else that is backing up Microsoft AG clusters with nodes that are hosted in different geographical DCs? 

We have the MSQL AG client configured at the moment to backup to “PLAN - DC1” but when the DBA’s failover the cluster to another node, the backups are being transfered across the WAN from “DC2” to “DC1” 

Should we not configure the backups using the AG for these DBs and confgure them on the clusters nodes instead and configure the storage polices to point to the Commvault Plan for that site or is there another option? 

Thanks for your time!

Hello @Alex Hay

If you have media agents configured at both sites you can leverage region based backups.

Documentation does not go in depth, but you would create a client group for each geo

If the AG client was put into both client groups how would Commvault determine the “region” that it is currently in?
